A progressive group is targeting Pennsylvania Sen. Pat Toomey with a new robocall campaign criticizing his opposition to considering a Supreme Court nominee this year.

In the calls by People For the American Way, actress Alfre Woodard urges voters to contact Toomey’s office and tell him "you expect him to put his Constitutional duties first—and give fair consideration to President Obama’s nominee."

The robocall script also criticizes Toomey for his remark to the Associated Press that "it's not that big a deal" for the Supreme Court to have a prolonged vacancy until the next president could put forward a nominee.

"He couldn’t be more wrong," states Woodard, whose film credits include "12 Years a Slave."

The robocalls will run tonight and Wednesday, and will target progressive voters throughout Pennsylvania, according to Laura Epstein, the organization’s spokeswoman.

The organization also has run similar calls in Wisconsin, where actor Martin Sheen – who played President Josiah Barlett on the television show, "The West Wing" – relayed the same message to recipients regarding Republican Sen. Ron Johnson.

On the other side of the issue, The Judicial Crisis Network, a conservative legal group, has launched a television ad campaign in Pennsylvania and elsewhere, praising Toomey and other swing-state GOP senators who have called for holding off on replacing Scalia.
